Its not work. I also try to colour changing. But this problem didn't solve

May I ask if this problem with only a specific thing, or in general ?

Hello, Im akash. I'm using mozilla Firefox. But somedays ago I saw my Highlight and bold text showing white colour with black stroke. You know our computer display showing white colour. For this reason It's very annoying for any kinds of user. Now I need to solve this problem.

Make sure you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.

Make sure you allow pages to choose their own colors.

• Options/Preferences -> General: Fonts & Colors -> Colors: "Override the colors specified by the page with my selections above"

Try "Never" if the default "Only with High Contrast themes" isn't working.
